SPRING-RETAINER FOR SLIDING SHOES.

Specification of Letters Patent.

Patented April as, 190s.

= vention is to adapt the sliding shoe for an easy and quick application to a tubular article, the tubes of which are of various diameter, the invention consisting of asplit in formed ofresilient material', having its ee ends suitably curved for their easy entrance into a tube, the lower or closed end of the pin being provided with a cone shaped collar o'r' a diameter at the larger end of the cone exceeding the interior diameter of thetube to which theretainer is to be applied, and below saidl collar, means for the attachment thereto of a sliding shoe, the improvement being illustrated in the accompanying drawing, in which,-- Y

Figure 1 is a vertical section of the lower end of a tube having therein my improvement in elevation, appliedY to a sliding shoe for furniture, shown in section vertically. Fig. 2 is a vertical section of the lower end of a tube,-having'my improvement in elevation applied to it, the surface, of the cone near the lower end of the split pin being in section,`

and of a different angle from the cone in Fig. 1, and the sliding shoe to which the retainer is attached being in section and of a diiierent construction from the one shown in Fig; l.'

Fig. 3 is an elevation showing a short piece of a tube, its upper end being in section, the

tube having improvement applied to it with another modification in the style of sliding shoe to which the bushing is attached.

Similar numerals and'letters indicate like parts in the several views.

' 1, indicates a piece of tube to whichiit is de,

sired to attach means for the easy moving of the article Aof which the tube is a part, the tube being'for instance, the post of an'iron or brass bedstead, or other article of furniture. The tubular posts of these bedsteads are' of various diameters and in order to provide av sliding shoe with means for its easy and quick attachment to thevarious sizes of-tubes, this retainer has beent devised. It consists.of a split pin of less than half the diameter of the tube with which it is'to be used, in the larger sizes of tubes in which they are designed to be used they being less than 1/6 of their diameter, the pins being formed of spring metal and having a cone shaped collar, the free ends of the pin being for centering and holding the upper end of the pin Within the tube, and the cone for centering its lower eiid and supporting the tube upon the cone. .The free ends 2 of the pin 3 are spreadapart and curved outwardly and then inwardly so that the resiliency of said ends will retain the pin within the tube while allowing itseasy entrance, only sufficient friction ofthe free ends within the tube being required to hold the pin and its attached sliding shoe from ropping out as the tube is raised from the oor.

, For holding the lower end ofthe pin in a central position within the tube, a cone 4 or 4a, is placed upon the pin, the shape of the cone beinggoverned by the use to which the bushing is to be put. of any desired taper, and` neither style will need to be fixed in position uponthe pin, but may be loosely mounted thereon and rest upon a narrow shoulder, 5.

The split pins may be made of any suitable size or form of material, having the necessary Hspring quality, but will usually be of half round st eel bars, and the cones may be vstamped -out of sheet metal, or cast, as their particular use may require. 6, 7, and 8, indicate'the sliding shoes. The shoes being connected with the split pin of the retainer by means of a universal joint of limited movement, owing to the large surfacewhichl they present for the support of the article to be moved, are easily slid along upon a rug or carpet without wrinkling it, or upon a bare floor -without 'm'arring the same.

Havin described my invention, what I These cones may be claim an desire to secure by Letters-Patent,

' -In a retainer for sliding shoes for -detachably connecting them with tubular legs of," furniture, the combination with a shoe of a pin of half the diameter or less, than that of the tube in which the pin is to be used, it being split into two leaves for part of its length their outer ends being spaced apart, and then curved inwardly and their extreme ends normally left separated fromeach other lfor their easy entrance into for filling the tube diametrically and for their retention therein, and a plain faced cone shaped collar mounted upon i the pin below its split adapted for centering i the pin, and for sustaining tubes ofdiiferent diameter thereon, substantially as set forth.
